Foldable bed unit

ABSTRACT

The present invention provides a middle rest of a foldable bed unit, which is typically set upon the middle portion of the foldable frame boards by pivoting two cross braces on the both sides of the vertical stems respectively, the another ends of the cross braces are pivoted on the frame boards respectively, wherein said cross braces extend out a stopper on each low end for touching against the both sides of the middle rest to hold the middle rest in right standing configuration, in this way, as tending to spread out the bed unit, said middle rest can be smoothly located on the middle portion of the frame board vertically without any offset happened under no artificial aid.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a foldable bed unit, and moreparticularly to a middle rest structure of a foldable bedstead.

2. Description of Prior Art

In accordance with the conventional foldable bed units, as shown in FIG.4, it is typically comprised of two half frame boards, two pair of endlegs separately on head and foot, and a middle rest; in which said twopair of end legs can be folded inward as folding the bed unit firstly,then lap over the two half frame boards in abutting, so that thefoldable bed unit is folded into a smaller quadrate for reducing thevolume occupied by the folded bed unit. Additionally, as spreading outsaid foldable bed unit, said middle rest is located on the middleportion of the bed board to prevent the middle portion from collapsing.Said middle rest is pivoted on the one ends of two cross bracesrespectively at the both sides, the another ends of said cross bracesare respectively pivoted on the two half frame boards for preventing themiddle rest from tilting as spreading out, in order to increase thesupporting stability. But the pivoting joint allows the middle rest ableto turn around the pivoting point, so that the middle rest has to beheld on in vertical position by user for functioning it as unfoldingover, so it will bring to be inconvenience in use.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide amiddle rest of a foldable bed unit that can be located in right attitudeautomatically without any artificial assistant as pitched up.

For achieving the above-mentioned object, the present invention providesa middle rest of a foldable bed unit, which is typically set upon themiddle portion of the foldable frame boards by pivoting two cross braceson the both sides of the vertical stems respectively, the another endsof the cross braces are pivoted on the frame boards respectively,wherein said cross braces extend out a stopper on each low end fortouching against the both sides of the middle rest to hold the middlerest in.

Said stoppers of the two cross braces touch against the both sides ofthe vertical sterns of the middle rest respectively for holding it in.

Said middle rest is shaped in H-shaped, and located by the stoppers ofthe cross braces at the both sides of the cross bar.

Said vertical stems of the middle rest have a U-slot built upon the topends of each respectively.

As utilizing above-mentioned project, due to holding coming from thestoppers of the cross braces at the both sides of the cross bar orvertical stems symmetrically for keeping the middle rest in verticalconfiguration, thereby as tending to spread out the bed unit, saidmiddle rest can be smoothly located on the middle portion of the frameboard vertically without any offset happened under no artificial aid; onthe other hand, said U-shaped slots built on the top end of the twovertical stems of the middle rest can catch on the cross member of saidframe boards as spreading out for making the supporting more stably.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1, a foldable bed unit provided by the presentinvention is typically comprised of two half frame boards 1, two pair ofend legs 2 and a middle rest 3, in which said middle rest 3 is inH-shaped, and the two vertical stems are pivoted on two cross braces 31respectively with the low ends, another end of said cross braces 31 arepivoted on the frame boards 1 respectively; wherein, said each crossbraces 31 extend out a stopper 311 on each low end for touching againstthe both sides of said vertical stem of the middle rest 3 to hold thevertical stems in locating configuration; on the other hand, the middlerest 3 has two U-slots 32 built upon the top ends of each vertical stemsrespectively.

As folding said foldable bed unit, as shown in FIG. 2, as same as theway of the conventional art, firstly inward fold the both end legs, thenlaps up the frame boards together to bend into a quadrate, as shown inFIG. 3. But, as tending to spread out said foldable bed unit, backwardsequence operation can be done, in this time, said cross braces 31pivoted on the middle rest 3 have stoppers 311 extended from the lowends respectively catching the cross bar of the middle rest 3 in fromthe both sides, so that the middle rest 3 is located in right standingconfiguration, further to supporting on the middle portion of said frameboards smoothly without any offset or title happened, meanwhile saidU-shaped slots 32 built on the top end of the two vertical stems of themiddle rest 3 can catch on the cross member of said frame boards asspreading out for making the supporting more stably.

On the other hand, said stoppers 311 extended from the low ends of saidcross braces 31 respectively catching the vertical stems of the middlerest 3 in from the both sides has the same effect of locating the middlerest 3 in right standing configuration, further to supporting on themiddle portion of said frame boards smoothly.
